note to self: lull "Russ Jones from Moz" into a false sense of security by publishing a low-quality "decoy" version of our post on the Ahrefs blog one day before he publishes his list on the Moz blog, then subsequently update our post with the better version :)

Dragon Metrics - for Chinese SEO's (keywords research, rank tracker, on-page audit and so on). I like this tool and using on a daily basis. Minimal design and maximum (a lot for sure) Chinese data. http://www.dragonmetrics.com/

Beamusup.com free basic site crawler. Makes an Excel, CSV or Google sheet output of basic technical SEO issues. Since it's a downloadable, it can crawl very large sites....if you can handle the very large file that would make. Totally free

The reality is for /BigSEO most of solution are build in house.
Those can provide the scale necessary to track million of keywords and the relative categorisations must have APIs handling the scale.
GetStat.com is by far one of those tools allowing /BigSEO to handle large scale tracking and building intelligence on top of data (share of real estate of the page, position, multiple categorization for agile testing, category movements, Google Products etc.). Master of all of the storage of HTML of the SERP, which allows data science and tracking overtime.
Other tools like Searchmetrics, SEMrush, Ahref are good for simple snapshots rather than deep dive grasping the complexity /BigSEO handle.
Screaming frog as few limitation as well, we tend to use internally for training purposes before moving to Splunk, far more comprehensive grated you can RegEX fluently.
Again at the risk of being repetitive but /BigSEO are likely to have 90% of tools built in house.
A few look at Pinterest Blogs and Etsy blog shed some lights to where and why most of solutions are built internally.

I like an Ultimate Keyword Hunter - it's free LSI research tool.
You need to download and install it on your computer.
Keyword Hunter analyzes keywords based on Google's top sites content and identifies themed keywords and phrases to be used in your article.
